Engineering Selection Recommendations

7M-20.000MAHV-T (TXC CORPORATION)

This substitute maintains identical electrical specifications to the main part with the exception of load capacitance (8pF versus 9pF). Both parts are manufactured by TXC CORPORATION within the same 7M series, ensuring design consistency. RoHS Compliance status is equivalent. The primary distinction is packaging format (Cut Tape versus Tape & Reel) and load capacitance variance of 1pF. Selection is appropriate when Cut Tape packaging is preferred for lower-volume applications or when 8pF load capacitance is compatible with circuit design parameters.

RH100-20.000-8-3030-EXT-TR (Raltron Electronics)

This Raltron Electronics substitute matches the 7M-20.000MAHC-T in physical dimensions (3.20 x 2.50 mm) and load capacitance (8pF). ESR is marginally higher at 70 Ohms compared to 60 Ohms. ROHS3 Compliance exceeds the RoHS Compliant status of the main part. Tape & Reel packaging format aligns with the main part. Selection is appropriate when Raltron Electronics sourcing is preferred or when ESR tolerance of ±10 Ohms is acceptable within circuit specifications.

R2016-20.000-10-3030-EXT-TR (Raltron Electronics)

This substitute represents a compact alternative with reduced physical dimensions (2.00 x 1.60 mm) and lower seated height (0.50 mm maximum). Load capacitance is 10pF and ESR is 200 Ohms, representing the most significant electrical variation among substitutes. ROHS3 Compliance status is equivalent to RH100 series. Selection is appropriate for space-constrained PCB layouts when ESR of 200 Ohms and 10pF load capacitance are compatible with circuit design requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute 7M-20.000MAHV-T for 7M-20.000MAHC-T in my design?

A: Yes. Both parts share identical frequency (20 MHz), frequency stability (±30ppm), ESR (60 Ohms), operating temperature range (-40 to 85°C), and package type (4-SMD, No Lead). The load capacitance difference of 1pF (9pF versus 8pF) is within typical application tolerance. Verify circuit design specifications for load capacitance compatibility before implementation.

Q: What is the primary difference between the TXC and Raltron substitute options?

A: TXC CORPORATION parts (7M-20.000MAHC-T and 7M-20.000MAHV-T) maintain identical ESR at 60 Ohms with load capacitance of 9pF and 8pF respectively. Raltron Electronics parts introduce ESR variations: RH100 series at 70 Ohms with 8pF load capacitance, and R2016 series at 200 Ohms with 10pF load capacitance. Manufacturer selection depends on sourcing availability and circuit tolerance specifications.

Q: Is the R2016-20.000-10-3030-EXT-TR suitable for my application if space is limited?

A: The R2016 series offers the smallest physical footprint (2.00 x 1.60 mm) and lowest seated height (0.50 mm) among all options. However, this part carries the highest ESR at 200 Ohms and load capacitance of 10pF. Compatibility depends on circuit design tolerance for these electrical parameters. Consult circuit schematics and oscillator design specifications before selection.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part 7M-20.000MAHC-T is RoHS Compliant. All substitute parts meet or exceed RoHS requirements: 7M-20.000MAHV-T is RoHS Compliant, while RH100-20.000-8-3030-EXT-TR and R2016-20.000-10-3030-EXT-TR are ROHS3 Compliant. All parts carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of packaging format differences (Tape & Reel versus Cut Tape)?

A: Tape & Reel (TR) packaging is standard for high-volume automated assembly processes. Cut Tape (CT) packaging is suitable for lower-volume applications or manual assembly. Both formats contain identical components; selection depends on production volume and assembly equipment compatibility. The 7M-20.000MAHC-T is supplied in Tape & Reel format.

Q: Can I use RH100-20.000-8-3030-EXT-TR as a direct replacement without circuit modifications?

A: The RH100 series maintains the same physical dimensions (3.20 x 2.50 mm) and seated height (0.80 mm) as the main part, enabling direct PCB footprint compatibility. ESR difference of 10 Ohms (70 versus 60 Ohms) and load capacitance of 8pF (versus 9pF) require verification against circuit design specifications. No PCB layout modifications are necessary if electrical parameters are within tolerance.

Q: What are the REACH and ECCN classifications for these parts?

A: All parts listed carry identical regulatory classifications: REACH Status is REACH Unaffected and ECCN is EAR99. HTSUS code is 8541.60.0050 for all crystal oscillator components in this comparison.
